UNITED h STATES? PATENT TOFFILJEO WASHINGTON RUMBLE, OF WHEELING,WEST VIRGINIA.

HEATl NG AND PUDDLING FURNACE.

SPECIFICATION forming part of Letters Patent No. 24S,059, dated October 11, 1881.

' Application filed May 20, 1881. (No model.)

To all 'whom 't may concern:

Be it known that- I, WASHINGTON RUMBLE, a resident of the city of Wheeling, in the county of Ohio and State of West Virginia, have invented certain new' and useful Improvements in Heating and Puddling Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the inrention, which will enable others skilled in the art to which it appertains to nake and use the same, reference being had to the accompanyin g drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to that class of heating and puddling furnaces in which heated air is .combined with the products of combustion for the purpose of igniting the unconsumed g'ases,

p and thereby increasingthe heat of the furnace; and to that end the invention consists in an improved Construction and arrangement of air-heating flues and passages in the crown and walls of the furnace, whereby the waste heat of the walls is utilized to furnish a supply of fresh hot air to aid in the combustion of unconsumed gases arising from the combustion-chamber.

In the drawings,Figurel is a vertical lengthwise section on line x x of Fig.`2, which is a. horizontal section on line 'n m of Fig. 1 ;`.Fg. 3, cross-section, k Zr, of Fig. 2.

Like letters of reference referto like parts.

The letters H H' designate the opposite walls of the furnace; H the roof or crown; A, the combu'stion-chamber; B, the grate; L, the bridge-wall; 0, the melting and puddling apartment; D, the smoke-stack; G, the ashpit.

The walls of the furnace are built preferably of ordinary clay brick, fire-clay brick being used for the lining of the heating and melting part of the furnace. The outside wall of the combustion-chamber is built with a series of vertical flnes, b, which open into and extend from the ash-pit upward and connect with an air-chanber, F, in the crown of the furnace. The bottom of these flnes is provided with a damper, d, or an equivalent shut-off device, to regulate the admisson of cold air.

K is a flue or air-passage in thebridgewall,

extending across the furnace to the side walls.

e e are flnes in the side walls, extending from the air-chanber F in the crown of the furnace and connectingwith the air-flueK in the bridgewall. i

c and a; are passages in the crown of the furnace and 'bridge-wall, respectively, for the admission of heated'iair to the conbustionchamber. These air-passages into the combustion-chanber areinclined toward each other and proportioned to suit. the exigencies of the case, and placed preferably near the throat of the furnace, as shown in Fig. 1, in order that the heated airnay thoroughly commingle with the smoke and gases and increase the draft, promoting thorough combustion before their passage into the melting-apartment. When the furnacefires are lighted the walls of the conbustion-chamber and the arched crown of the same are the parts that first receive the heat, and when the fire becomes sufficiently hot the tdamper is opened and the cold air admitted gradually in requisite quantities. When the furnace is in full operation the walls and crown of the combustion-chanber, including the bridge-Wall, are constantly at ahigh red heat, and the atmos'pheric air, in being drawn through the flues 'by the draft of the furnace,

is raised to ahigh degree of heat before it enters into the hot gases at the crown of the combustion-chamber, where it unites in combustion with them, serving in a great neasnre to consune the smoke before its passage into the heating and melting apartment, thus'de- V `creasin g the liability of inj urious efiects of the unconsuned smoke and in treatment.

By connecting the hollow bridge-wall with the air-chanber I am enabled to control the inflow of air with one (lamper or regulating devic`e, andI also obtain a division of the inflow to the combustion-chamber on opposite sides gases upon the metal of the throat of the furnace, whereby the air can readily combine in free conibustion with the gases in the furnace.

The advantages of hollow walls to prevent the rapid burning out and destructiou of the same are obvious and need not be specially referred to.

Having described my invention,what I claim, and desire to secure by Letters Patet of the United States, is i In a puddling-furnace, the combination of IOO the air-chanher F in the crown of the furuace, my own I he'eunto afix my signature in pres:
